ViperEkura 5244f1a8fc feat: add te-style scaled fp8 training via fp8_autocast ...

- per-tensor scales applied inside cublasLt via A_SCALE/B_SCALE
- delayed scaling: weight amax history ring, refresh every 16 steps
- quantize kernels emit atomic amax, device-side scale updates
- fp8_autocast context toggles aten::linear dispatch like torch.autocast
- fallback to bf16 when M/N not 16-aligned (fp8 gemm constraint)
- x/g scales delayed one step, reuse free atomic amax (no abs/max reduce)
